Mycroft is a very complex character. Will we see much more of him?
Yes, there’s an upcoming shower scene. Mark’s going to the gym already. Other than that, yes, we love Mycroft. Became a much bigger, more important than we expected, especially in Scandal. Somehow - for me, anyway - he’s the key to Sherlock. Imagining that past, those boys, that home….
Is there any significance of the ring on Mycroft’s right hand?
It has a concealed laser. Probably.
